The UK Debt Management Office (DMO) was established on 1 April 1998. The DMO's remit is to carry out the Government's debt management policy of minimising financing costs over the long term, taking account of risk, and to minimise the cost of offsetting the Government's net cash flows over time, while operating in a risk appetite approved by Ministers in both cases.

Due to the specialist technical nature of the roles within the Agency, there is no hierarchical grading structure below SCS level. For the purposes of the organogram all posts have been split into two generic categories of staff; those of the Policy & Markets staff, who are involved with the core activities of interpreting government policy and executing gilt and cash dealing activities; and those of Operations & Resources, who provide the infrastructure to support the core activities.

Staff are remunerated according to the nature of their role, more often than not with a background from the financial services sector, and therefore the DMO does not operate with either a grading structure or pay bands.

In the organisation chart, the resource costs have been given for the two areas of Policy & Markets and Operations & Resources, where a number of teams have fewer than 5 FTE staff. Data have therefore been aggregated where this could otherwise lead to the identification of protected personal data about individual staff members.
